Peck Gail M 4

What Happened Gail M. Peck, Chief Financial Officer of Arcosa, Inc. (ACA), received an award of 15,075 shares (reporting code A) on 2026-03-15. To cover tax liabilities related to the award (reporting code F), 7,744 shares were withheld/disposed at $105.68 per share, generating $818,386. Based on the withholding price, the full award was worth roughly $1.59M; the net newly retained shares from the award equal 7,331 (15,075 − 7,744). This transaction reflects a company award/vesting event and a routine tax-withholding sale, not an open-market purchase or directional sale by the insider.

Key Details

• Transaction dates: March 15, 2026; Filing date: March 17, 2026 (Form 4 accession 0001739445-26-000042).
• Award: 15,075 shares acquired at $0 (grant/vesting). Withholding: 7,744 shares disposed at $105.68, proceeds $818,386.
• Implied award value (using $105.68): ≈ $1,593,126; net shares retained from this award: 7,331.
• Shares owned after transaction: not stated in the filing (filing shows award and withholding but does not disclose total post-transaction holdings).
• Footnote/transaction codes: A = Award/Grant; F = Payment of exercise price or tax liability (tax withholding). This appears to be a standard tax-withholding/settlement on vesting, not a discretionary sale.

Context

• This looks like a typical restricted stock/RSU vesting event with shares withheld to cover taxes (cashless withholding). Such withholding is administrative and does not necessarily signal insider sentiment about the stock.
• For retail investors, purchases are generally more informative about insider conviction; awards and tax-withholdings are routine compensation mechanics.
